Abstract

A copper base brazing alloy has the following composition by weight:- .Ni............20 to 40% .In............0 to 10% .Si............0 to 4% .Cu............balance, Si being 4% with In absent, and In 2 to 10% when Si is 0 to 3% A preferred alloy consists of 35-38% Ni, 4-6% In and 61-56% Cu. A mixture of powdered alloys for brazing may consist of 75 to 95% of the above alloy, up to 24% of a nickel base alloy containing 1.5-2.4% Si and 0.5-1.8% B, and up to 15% of a nickel base alloy containing 3-5% Si, 2.5-3.5% B and 6-8% Cr. The mixture may be used for brazing a high temperature nickel base bearing alloy having the following composition by weight:- .C ............0.06 to 0.20% .Cr............18 to 20% .Co............9 to 12% .Mo..........9 to 10.5% .Ti............3 to 3.3% .Al............1.5 to 1.9% .B ............0 to 0.02% .Ni............balance
